Episodic zooplanktivory by largemouth bass (Micropterus salmoides) on Daphnia: a 25-year natural history record from a small northern temperate lake

Journal of Freshwater Ecology, 2020
We observed episodic zooplanktivory by largemouth bass (Micropterus salmoides; LMB) ≥ 150 mm total length (TL) on the cladoceran Daphnia spp. over two decades in a small oligotrophic lake. While zooplanktivory is beneficial for young-of-year and juvenile

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Integrating anaerobic and photochemical processes: UV–vis‐driven post‐treatment for micropollutant abatement and toxicity control in UASB secondary effluent

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Upflow anaerobic sludge blanket (UASB) reactors are widely used in low‐ and middle‐income countries, but secondary effluents may still contain organic micropollutants and residual toxicity. This study evaluated UV–Vis photolysis and UV/H2O2 as post‐treatment options for UASB secondary effluent (SE), integrating micropollutant ...

Oleic Acid‐Mediated Double Emulsification Enables Enhanced Aqueous Stability and Localized Photothermal Heating of Liquid Metal Droplets

Small Methods, EarlyView.
Oleic acid‐mediated double emulsification creates a yolk–shell‐like liquid metal photothermal platform in which the intermediate oil phase limits water transport to the liquid metal and reduces convection‐mediated heat dissipation from the irradiated region.

Dispersion and sedimentation of titanium dioxide nanoparticles in freshwater algae and daphnia aquatic culture media in the presence of arsenate

Journal of Experimental Nanoscience, 2018
Little information is available on Titanium dioxide nanoparticles (nTiO2) behavior in different culture media for aquatic organisms. This study aimed to accurately evaluate nTiO2 dispersion and sedimentation in common freshwater algae (BG-11) and daphnia

The stable isotopic composition of Daphnia ephippia reflects changes in δ¹³C and δ¹⁸O values of food and water [PDF]

Biogeosciences, 2015
The stable isotopic composition of fossil resting eggs (ephippia) of Daphnia spp. is being used to reconstruct past environmental conditions in lake ecosystems.

Influence of Age and Exposure Pathway on Copper and Cadmium Mixture Toxicity: A Study on Daphnia magna

Environmental Toxicology, EarlyView.
ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

Artemia salina Toxicity Assay: Standardization in a 24‐Well Microplate

Environmental Toxicology, EarlyView.
ABSTRACT Bioassays with Artemia sp. are widely used in aquatic, environmental, and human toxicology as an initial tool to investigate the toxicity of plant extracts, isolated compounds, drugs, and products of natural or synthetic origin. These assays allow for the estimation of the median lethal concentration (LC50) and guide subsequent studies in ...

The visual ecology of selective predation: Are unhealthy hosts less stealthy hosts?

Ecology and Evolution, 2021
Predators can strongly influence disease transmission and evolution, particularly when they prey selectively on infected hosts. Although selective predation has been observed in numerous systems, why predators select infected prey remains poorly ...
